Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20170830' into staging

First batch of s390x patches:
- 2.11 compat machine
- support the new --s390-pgste linker option, making it possible to
  avoid enabling the global vm.allocate_pgste systl if all pieces
  are in place
- correctly identify some devices as not hotpluggable
- clean up some tests and enable them for s390x
- wire up the diag288 watchdog in tcg
- clean up dependencies on CONFIG_PCI, making it possible to disable
  it by hand
- lots of cleanup in target/s390x/
- fix alignment of the ccw1 structure in the s390-ccw bios
- and some more bugfixes
